(DFA) VCI
—The virtual channel indicator (VCI) number corresponding to the DFA
field:
0...63
. This parameter defines the selected VPI for Mapping to/from the Port
card (Router) to the trunk.
(DFA) VCI Range
—The DXI virtual channel indicator range:
1...32
. This parameter
defines the range of VCs starting from the one selected, in twos. and allows quick
input of multiple VCCs.
Shaper Number
—Select one of the 15 Shaper values that you configured under
Manage Card
. You assign the
Shaper
value to ensure adequate traffic flow to and
through the ATM WAN. The
Shaper
parameter is key in ensuring that your traffic
does not exceed the negotiated traffic contract as administered by the service
department or IS department.
Early Packet Discard
—Enables or disables early packet discard. For every
connection where early packet discard is enabled, a status is kept when there is a
partial packet for that connection in the queue. Once the queue cell level exceeds
the congestion ON thresholds, only connections with partial packets already
existing in the queue are allowed in. Cells from other connections are dropped.
HDLC/SDLC Virtual Circuit Parameters
If the serial port is configured as a
HDLC/SDLC port, you must set the following virtual circuit parameter:
Shaper Number
—Select one of the 15 Shaper values that you configured under
Manage Card
. You assign the
Shaper
value to ensure adequate traffic flow to and
through the ATM WAN. The
Shaper
parameter is key in ensuring that your traffic
does not exceed the negotiated traffic contract as administered by the service
department or IS department.
